Abstract

Racing tyres for cars and motorcycles must be preheated to working temp. before a race by a warm-up round of e.g. 6 miles. The high risk of accidents during this run has induced efforts to achieve this without any warm-up run. This has been achieved by applying a bandage of a hybrid carbon/glass fibre weave with longitudinal carbon fibres as heat conductors and glass fibres as insulators. Pref. the tyre warm-up bandage (1) consists outside of a flexible tear-proof textile material (2) with several flat cavities (4) sepd. by seams (3). Electrically heated C fibre conductors (5) have terminals (6) and glass fibre weft threads (9) to keep them apart and insulated, in addn. to warp glass threads. Crimp sleeves (10) are joined to a thermostat (12). A glow lamp (13) indicates that the power is ON. The cords (8) are used to tighten the bandage around the tyre. Heat losses are minimised by insulation (7). ADVANTAGE - This achieves a uniform preheat without local superheating and is easy to match various tyres. The 3 mm thickness facilitates its application. This method cuts out any risk of accidents.

Description

AnmeldegegenstandSubject of registration

Die Erfindung bezieht sich auf eine elektrische Heizvorrichtung zur Vor- bzw. Anwärmung von Motorrad- und Auto-Rennreifen auf Betriebstemperatur.The invention relates to an electric heating device for preheating and warming up motorcycle and car racing tires Operating temperatur.

Stand der TechnikState of the art

Ein Rennreifen haftet optimal nur bei einer bestimmten Be­ triebstemperatur. Er muß daher zuerst warmgefahren werden (ca. 10 Kilometer Fahrstrecke).A racing tire adheres optimally only to a certain loading operating temperature. It must therefore be warmed up first (approx. 10 Kilometers driving distance).

Es gibt derzeit nur wenige Lösungsansätze um Reifen vorzuwärmen, so daß man von einem darüber hinausgehenden Stand der Technik kaum sprechen kann. Es existieren Versuche mit ganzen Heiztaschen, in die die kompletten, vorher zu demontierenden Räder gesteckt werden. Andere Lösungsversuche beheizen zwar nur die Lauffläche, verwenden aber als elektrische Leiter wenige metallische Drähte.There are currently only a few approaches to preheating tires, so that one hardly ever goes beyond a state of the art can speak. There are experiments with whole heating bags, in which put the complete wheels to be dismantled beforehand will. Other attempts at solution only heat the tread, but use few metallic wires as electrical conductors.

Kritik am Stand der TechnikCriticism of the state of the art

Das Warmfahren birgt erhebliche Risiken in der Anfangsphase eines Auto- oder Motorradrennens. Durch eine sogenannte Warm-up-Runde wird vor manchen Rennen versucht dieses Risiko zu vermindern.Warming up poses considerable risks in the initial phase Car or motorcycle racing. Through a so-called warm-up round attempts are made to reduce this risk before some races.

Der Nachteil der Taschenmethode ist, daß die Räder zum Aufwärmen komplett demontiert und danach wieder montiert werden müssen. Vom hohen Aufwand einmal abgesehen, werden unnötigerweise auch die Felgen beheizt. Außerdem geht alleine durch die für die Wieder­ montage der Räder benötigte Zeit Wärme verloren und vermindert den erwünschten Effekt.The disadvantage of the pocket method is that the wheels warm up completely disassembled and then reassembled. From apart from the high effort, those are unnecessarily Heated rims. Also go through those for the re alone assembly of the wheels lost time and reduces heat desired effect.

Der Nachteil der Lösung mit metallischen Leiterbahnen auf Drahtbasis ist,The disadvantage of the solution with metallic conductor tracks Wire base is

  • - daß wegen der geringen Kontaktfläche der Draht eine zu hohe, den Reifen schädigende Temperatur haben muß, um eine Gesamtauf­ wärmung in gegebener Zeit zu erreichen.- That because of the small contact area of the wire is too high, the Tire must have a damaging temperature to make up a total to achieve warming in due time.
  • - daß es leicht zum Durchstoßen oder -scheuern des Mantelgewebes und damit zu Elektrounfällen kommen kann.- That it is easy to pierce or chafe through the sheath fabric and can lead to electrical accidents.
  • - daß die Wärmevorrichtung (bei einer Länge von ca. 2 Meter) wegen der begrenzten Flexibilität und Dauerbiegefestigkeit des Heizdrahtes nur mit hohem Platzaufwand gelagert werden kann und es bereits beim vermehrten, engerem Zusammenrollen/-legen zu Drahtbrüchen und damit zum kompletten Funktionsausfall kommen kann.- Because of the heating device (with a length of about 2 meters) the limited flexibility and fatigue strength of the Heating wire can only be stored with a lot of space and it already with the increased, closer rolling up / laying Broken wires and thus complete functional failure can.
Aufgabetask

Der Erfindung liegt die Aufgabe zugrunde das beträchtliche Unfallrisiko wegen reduzierter Haftfähigkeit kalter Auto- und Motorrad-Rennreifen von Fahrtbeginn an zu beseitigen. Weiter muß schnell, einfach und betriebssicher die erwünschte Reifen­ vorwärmung am Fahrzeug ohne Demontage der Räder oder von Fahr­ zeugteilen (z.B. Schutzbleche, Kotflügel) durchzuführen sein ohne die oben beschriebenen Nachteile.The invention has for its object the considerable Risk of accident due to reduced adhesion of cold car and Eliminate motorcycle racing tires from the start of the journey. Further must the desired tires quickly, easily and reliably Preheating on the vehicle without dismantling the wheels or driving parts (e.g. fenders, fenders) must be carried out without the disadvantages described above.

Lösungsolution

Der Reifenwärmer (1) besteht in der Außenschicht aus einem flexiblen und reißfesten Textilmaterial (2) und weist je nach Breite mehrere, durch Nähte (3) begrenzte, flache Hohlräume (4) in Längsrichtung auf, welche die durch elektrischen Strom erwärmten Kohlefaser-Heizleiter (5), deren elektrische Verschaltung und Anschlüsse (6), eine thermische Isolierlage (7) nach außen zur Vermeidung von Wärmeverlusten und seitlich die Befestigungs- Spannschnüre (8) aufnehmen.The tire warmer ( 1 ) consists of a flexible and tear-resistant textile material ( 2 ) in the outer layer and, depending on its width, has several flat cavities ( 4 ) in the longitudinal direction, delimited by seams ( 3 ), which contain the carbon fiber heating conductors heated by electrical current ( 5 ), their electrical connections and connections ( 6 ), a thermal insulation layer ( 7 ) to the outside to avoid heat loss and the fastening strings ( 8 ) on the side.

Die Kohlefaserheizleiter sind Bestandteil eines Kohlefaser-/Glas­ faser-Hybridgewebes, in dem die Kohlefasern (5) unidirektional, d.h. in Längsrichtung (Kettfäden) verlaufen. Durch quergerichtete Glasfasern (Schußfäden) (9) werden sie fixiert und durch zusätzliche längsgerichtete Glasfasern pysikalisch voneinander getrennt und elektrisch isoliert.The carbon fiber heating elements are part of a carbon fiber / glass fiber hybrid fabric in which the carbon fibers ( 5 ) run unidirectionally, ie in the longitudinal direction (warp threads). They are fixed by transverse glass fibers (weft threads) ( 9 ) and physically separated from one another and electrically insulated by additional longitudinal glass fibers.

Dies erlaubt es, die einzelnen Kohlefasern (5) durch eine komplexe Kombination von elektrischen Serien- und Parallelschaltungen unter Verwendung von Preßhülsen (10) an den Enden so miteinander zu verbinden, daß auf Basis von 220(110) Volt über einen Euro-Norm­ stecker (11) an jeder Steckdose ohne einen weiteren elektrischen Vorwiderstand genau die für die Anwendung richtige Heizleistung erzielt wird.This allows the individual carbon fibers ( 5 ) to be connected to one another by a complex combination of electrical series and parallel connections using compression sleeves ( 10 ) at the ends in such a way that, on the basis of 220 (110) volts, they are connected via a Euro standard ( 11 ) Exactly the right heating output for the application is achieved at every socket without an additional electrical series resistor.

Zur Regelung der Reifentemperatur dient ein Thermostat (12), der zwischen Reifen und Reifenwärmer eingelegt wird.A thermostat ( 12 ), which is inserted between the tire and the tire warmer, is used to regulate the tire temperature.

Zur Überwachung von Funktion und Regelverhalten dient eine Glimmlampe (13) .A glow lamp ( 13 ) is used to monitor function and control behavior.

Erzielbare VorteileAchievable advantages

Ein Warmfahren der Reifen und das damit verbundene hohe Unfall­ risiko in den ersten Runden eines Auto- oder Motorrad-Rennens entfällt.Warming up the tires and the resulting high accident risk in the first laps of a car or motorcycle race not applicable.

Wegen der großen Anzahl der in Umfangsrichtung verlaufenden Kohlefasern kann die Wärmeübertragung absolut gleichmäßig, schnell und ohne lokale Überhitzung (und damit Schädigung) der Reifen­ oberfläche erfolgen.Because of the large number of circumferential Carbon fibers can heat transfer absolutely evenly, quickly and without local overheating (and therefore damage) of the tires surface.

Wegen der sehr geringen Dicke des Reifenwärmers (ca. 3 mm) kann er ohne weitere Maßnahmen durch Drehen des Rades auf die Lauffläche aufgezogen und durch einfache seitliche Spannschnüre fixiert wer­ den. Die Entfernung kann unmittelbar vor Einsatz des Fahrzeuges ohne großen Wärme-/Temperaturverlust erfolgen.Because of the very small thickness of the tire warmer (approx. 3 mm) it can without further measures by turning the wheel on the tread wound up and fixed by simple lateral tension cords the. The distance can be immediately before using the vehicle without great loss of heat / temperature.

Wegen des Textilcharakters von Hülle und der elektrischen Heizlei­ ter ist leichte Verarbeitbarkeit, minimale Bauhöhe, maximale An­ paßbarkeit an unterschiedliche Reifendurchmesser und Reifenbrei­ ten, große Flexibilität bis hin zur Knickfestigkeit, Service­ freundlichkeit durch Austauschmöglichkeit einzelner Heizbahnen, Reinigungsmöglichkeit sowie hohe elektrische Sicherheit gewährlei­ stet.Because of the textile character of the cover and the electrical heating element ter is easy to process, minimum height, maximum load adaptability to different tire diameters and tire width ten, great flexibility up to kink resistance, service friendliness due to the possibility of exchanging individual heating tracks, Possibility of cleaning as well as high electrical safety continuous
